This invention relates to containers, particularly to those made fromspirally wound and overlapped strips, as paper, forming paper bottles orother Vforms of paper containers.

Containers of various kinds have been made of thin material, which ishad in the market in sheet form, as well as in long continuous strips,wound .in rolls, for ready use, in the various trades. Considering paperas a cheap and serviceable material from which to make a manufacturedand practical container, having a progressively convergent wall, eitheras the whole side wall of a container, or a portion thereof,particularly as one simulating the form and size of a given bottle, andconsidering also, that we are to use paper of suitable thickness andquality as it comes in the form of rolls, it is our main object toprovide a tapered wall structure to said container, which can be readilymanufactured, when produced in large quantities, and which structurewill lend itself to the use of strips, spirally wound in overlappingrelation, in forming the tapered Wall.

It is our further object, in connection with said tapered wall, toprovide a form of a contraction or shortening to one edge part of saidstrips, by

Way of a series of overlapped plaits, created in the advancing edge partof the strips, as the same are wound in spiral relation upon aconvergingly tapered mandrel, considering here, not the method of makingthe bottle, but rather the resultant Vcontainer structure, so formed andembodied in the tapered wall portion, wherein the overlapped and plaitedstrips are glued or cemented together. Such a wall structure may beembodied in a paper bottle made for milk or one having a differenttapered portion, where the bottle is to be used for oil or othermaterial.

A further object is to provide such a bottle as will fulll any or all ofthe above named objects and at the same time be lighter and much cheaperthan the glass bottle, which it is designed to replace. We desire toprovide such a paper bottle which can be made automatically, Withoutmuch handling in the making, and at a cost which will Warrant its beingthrown away after a single use.

In making such a. bottle to be lighter than a glass bottle of a givensize, it is our desire to save in the weight item of handling milk, oil,and other bottles, so that more paper bottles of like capacity can becarried, than glass bottles, in a delivery truck, per trip, and being ofa shape simulating the glass bottle which it replaces, it will be adaptyed to lt the carriers now used for the glass bottles.

Another object is to provide a form of paper bottle of the classdescribed, which will afford a substantial and rigid constructionfulfilling all of the form and strength requirements now fulillled bythe glass bottle, yet` eliminating the breakage factor common to glassbottles, as a cutting danger both to automobile tires and to persons.

A further object is to provide a paper bottle which will particularlysimulate the usual form of motor oil glass bottles, having a longtapered neck portion, and having a dat cap or disc closure. In additionwe wish to provide a cap c1o. sure that is formed by machinery to beilxed in place and is not releasable, once the paper bottle is filledwith oi1,'requiring the cutting oif of the bottle top, with its cap, torelease the contents of the bottle, thus destroying its use for a refllland at the same time, making the mutilating oi' the bottle noticeable,if an attempt is made to substitute another and inferior oil, once thebottle of oil is received by a dealer to be sold retail.

A special cheap tool can be provided lor cutting oi the top of thebottle.

With these and other objects, which will hereinafter appear, ourinvention resides in certain forms of construction. lVarious embodimentsof our invention are illustratedin the drawings and are hereinafterdescribed and what we claim is set forth.

In the drawings, AFigure 1 is an elevation, partly broken away, showinga nished form of paper `,milk4 bottle, embodying our invention. Figure 2is a top plan of the bottle shown in Figure 1.

Figure 3 is an elevation, partly broken away,A showing the bottleillustrated in Figure 1, but here in an unnished condition, with diesshown in section, for shaping the ends.

Figure 4 is an elevation, partly broken away,

showing a finished form of lled paper oil bottle,l

with the cap cover secured in place.

Figure 5 shows a perspective view of a fragment of strip as part of atapered wall structure, wherein the upper edge of the strip is showncontracted or shortened by a series of overlapped plaits. r y

In the figures, two forms of paper bottles are Y shown, one form beingthat of a milk bottle and the other form being that of an oil bottle.Considering rst the paper milk bottle, that marked 15, illustrated inFigures 1, 2 and 3, has a wall 16, made up of inside and outsidelaminated paper strip portions. These wall portions 17 and 18 are formedindependent of one another, except that they are cemented together. Eachof the portions 17 and 18 is formed of a plurality of overlapping andcontinuously wound, spiral layers of paper strip19, wherein the stripsoverlap one another, so as to provide a multiple thickness of paper toeach of the Wall portions 17 and18. According to the width of paperstrip used and the amount of overlap for each convolution of thesucceeding spiral coils of paper wound on, one can form as thick a wallportion as desired, according to the overlap and number of overlappedwindings used, and have as many suchl wall portions as will give him thethickness of bottle wall required.

There is a bottom disc 20, of paper, having a flange 21, which is curledup to lock the bottle bottom both ways, to iix it therein. The mouth 22,of the bottle is formed with a cap seat 23, and a built-up flange 24,wherein several thicknesses of paper are wound together. The bottle isshown to have a cylindrical portion 25, extending from the bottom disc20 to the point 26, where the bottle tapers convergently upward, havinga reverse curve in vertical section, as shown in Figure 1, andterminates in the neck 27. The tapered portion 28, extending from thepoint 26, to the neck 27, is made up .of tucked-in spiral, overlappingstrips, wherein the small, short, vertical markings 28, on the figure,represent the multiplicity or series of tucks or overlapped plaits, ofthe paper strip coils, forming a contraction or shortening of the upperedge portion of the strip to conform to the gradual reduction in thecircumference of the tapered portion 28, of the bottle, as we advancetoward the mouth 22. A protective coating 29, of any suitable substance,as wax or lacquer, covers the bottle inside and out.

The long oil-bottle 30, shown in Figure 4 is similar in construction tothat of the milk bottle, illustrated in Figure 1, except as to its top31, and the form of the tapered portion 32, of the bottle 30.

The wall 33, of the bottle 30, has a cylindrical portion 34 and aconical portion 35, the upper part of which forms a neck 36, above whichis the mouth 37. The cap 38, resting on the seat 39 is secured in placeby rolling in the top part 40, of the bottle wall, as at 41. The flangedporl tion 42, at the mouth 37, of the bottle, is made up of extrawindings of paper and is formed by being compressed in dies, as is theflange 24, of the milk bottle 15. While the oil bottle 30, shown inFigure 4, is first formed with an open outh,

lit'is here shown with the cap 38 fixed in` place,

as it will be when illled with oil orother material, ready for themarket. A protective coating 44, of suitable lacquer or other substance,covers the bottle 30, inside and out.

In Figure 5 we have illustrated a Vstrip fragment, such as one from thetapered wall portion 28, and show a series of overlapped plaits 28H.

Tapered wall portions of other containers than those illustrated anddescribed can be similarly formed of strips, having the contracting orshortening of an edge portion formed 'by creating therein a series ofoverlapped plaits.

Containers formed of coiled strips glued together in spiral relation,and particularly those having tapered portions made in accordance withthis invention, are very strong and durable, as well as being light andleakproof, where a suitable adhesive is used. And the compressedformation of the mouth permits of the same kind of handling for iillingand capping particularly using a sheet metal cap, either one rolled onor one such as a crown cap, as is done now with glass bottles. Besides,the great stiffness of a bottle embodying our invention makes itreliable in withstanding top pressures attending the use of cappingmachines, as well as in handling, after being capped. The cheapness withwhich such paper bottles can be made, permits of throwing them awayafter one use. When such a form of bottle, as illustrated in Figure 4,is made with a rolled-in top, after iilling and capping the bottle forthe retail trade, the top can be cut oi to discharge the oil, or whereya cap shield of rolledaround, sheet metal is used, it can be torn oir inthe usual way when opening the bottle, as is now done with glassbottles.

Inasmuch as changes can be made diiering from the embodiments-of ourinvention, as herein shown and described, without departing from thespirit and scope of our inventi we wish to include all changes whichcome wit in the purview o! the following claims.

We claim,

1, In a container, a body wall, a tapered portion to said body wall,said tapered portion being formed of coiled strips, overlapping oneanother in spiral relation, said strips having that edgek part, which istoward the converged end of said tapered portion, contracted orshortened by a series of overlapped plaits.

2. A container formed of a body wall, a bottom closure to said wall anda mouth, a tapered portion to said wall, said tapered portion beingformed ofcoiled strips overlapping one another in spiral relation, saidstrips having that edge part which is positioned toward the convergedend of said tapered portion formed of a series of overlapped plaits, soas to contract or shorten said edge to form a converged wall.
